To further improve emissions compliance, the 3.5-liter V6 makes use of an after-catalytic-converter exhaust gas recirculation (EGR) system that allows cleaner, cooler EGR gas to be fed back into the intake system. An EGR system, especially one that delivers a cleaner, cooler charge, reduces pumping loss for better fuel efficiency. With its 60-degree V-angle and compact, rigid and lightweight high-pressure die-cast aluminum cylinder block assembly, the 3.5-liter V6 powerplant is exceptionally smooth during operation. Other factors that help reduce engine noise and vibration are a rigid forged-steel crankshaft, die-cast accessory mounts, and a stiff cast-aluminum oil pan that reduces cylinder block flex.
A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm-up and operating cylinder liner temperatures to reduce friction. Plateau honing of the cylinder lining further reduces friction between the piston skirts and the cylinder walls by creating an ultra-smooth surface. This 2-stage machining process uses two grinding processes instead of the more conventional single-stage honing process. Plateau honing also enhances the long-term wear characteristics of the engine. Designed with "cavity-shaped" crowns, the 2018 Odyssey pistons help maintain stable combustion and contribute to stratified-charge combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. Heavy-duty steel connecting rods are forged in one piece and then "crack separated" to create a lighter and stronger rod with an optimally fitted bearing cap.
The new fifth-generation Odyssey is a progressive and sporty evolution of the Odyssey well-known exterior form. In front, the 2018 model includes the latest version of Honda trapezoid grille, with boldly restyled chrome bars, stylized headlights, and new wing-shaped LED daytime running lights (DRL) lending a premium appearance on EX and above models. Bright LED headlights and fog lights complete the Touring and Elite trims. The hood gains new character lines that add a more visually enticing and sophisticated look, while the front fascia invokes a sports sedan, with a large lower air inlet.
Exclusive to the Odyssey Touring and Elite trims, LED low- and high-beam headlights provide improved nighttime illumination and visibility compared to contemporary high-intensity discharge (HID) headlights. Six LEDs serve as low beams and three LEDs serve as high beams on each side. Besides improving driver confidence and passive safety, the LED headlights use less energy, helping to enhance fuel efficiency by reducing engine loads. In addition, the LED headlights last up to five times longer than HID headlights and up to 10 times longer than halogen headlights - contributing to less frequent replacement and the associated cost savings. An auto on/off function is also included.
